摘要：

The tensile properties of basalt fiber reactive powder concrete (BFRPC), were investigated using the splitting tensile test of 90 specimens and axial tensile test of 12 specimens. The effect of the water-binder ratio (0.20, 0.22, and 0.24), basalt fiber length (12 and 6 mm), fiber volume fraction (0, 0.05, 0.10, and 0.15%), and curing age (7 and 28 d) on the tensile properties of BFRPC was evaluated. The results show that the basalt fiber significantly increased the splitting tensile strength. The fiber 12 mm long has little effect on the early strength development of concrete, while its early strength with fiber 6 mm long is slightly lower. The calculation formula for the stress-strain curve of BFRPC was derived.
